Sergio Perez has promised to be less aggressive if he finds himself wheel-to-wheel with McLaren team-mate Jenson Button again.

Perez and Button made contact on track at the last race in Bahrain as they vied for position. After the incident the Mexican said he had not apologised to Button, but during the press conference for the Spanish Grand Prix admitted he would be more careful in the future.

"We were far too aggressive with each other, we lost time and I think that has to be a little bit different between us," Perez said. "We shouldn't waste too much tyre, especially at this stage of the season where the tyre is so critical. We are wasting too much tyre if we fight that hard, so I think we have to be more flexible in the fight. We are thankful that we are in a team like McLaren which lets you fight as team-mates, so in that respect we have to respect each other a bit more."

He said he had apologised to the team and repaired his relationship with Button between the races.

"Jenson and myself talked firstly to apologise to the team because we were quite aggressive, we were close to having an accident," he said. "The chat was mainly to clear the air, to say everything that we thought between us and to clear the relationship, because at the moment, especially, we need to be together to come out of the position that we are in where we are not quick enough at the moment, and we have to keep working very closely, Jenson and myself. I think the chat that we had with Sam [Michael] and Martin [Whitmarsh] helped to keep the relationship strong and to keep the team together and get out of the difficult moment. The chat was mainly for that."
